“…There is very little reliable information on vector-borne agents in dogs in China with only eight reports for the entire country: three using serology (7, 10, 11), one using PCR (13), three using serology and PCR (9, 14, 15), and one using PCR and microscopy (12). Studies with PCR and/or serology methods have indicated the E. canis occurs in dogs from Shenzhen, Guangzhou and Hong Kong [ 7 – 9 ] and D. immitis in dogs from Beijing, Shanghai, Chongqing, Yunnan, Guangdong and Shenyang provinces/ municipalities [ 7 , 10 , 11 ]. Molecular based studies have shown D. immitis in dogs from Liaoning province [ 12 ] and leishmaniasis to be common in dogs in Sichuan province [ 13 – 15 ].…”

BackgroundAlthough many vector-borne agents are potential zoonoses and cause substantial morbidity and mortality in dogs worldwide, there are limited data on these organisms in dogs of China.MethodsQuantitative PCRs for vector-borne agents were performed to investigate their prevalences in convenience whole blood samples obtained from 1114 dogs from 21 veterinary clinics and a commercial dog breeding facility in ten provinces of China. In addition, the PCRs were performed on 146 Rhipicephalus sanguineus senso lato and 37 Linognathus setosus collected from dogs in the commercial dog breeding facility.ResultsDNAs of Babesia gibsoni and B. vogeli (1.2 %), Ehrlichia canis (1.3 %), Hepatozoon canis (1.8 %) and Theileria orientalis (0.1 %) or a closely related organism were detected in the bloods of the dogs studied, and Babesia vogeli (3.4 %) and Ehrlichia canis (4.1 %) in R. sanguineus senso lato. The qPCRs for Anaplasma spp., Dirofilaria immitis and Leishmania spp. were negative for all blood samples, ticks and lice. At least one vector-borne agent was found in dogs from 5 of the 10 provinces investigated in this study. Overall, 4.4 % (49/1117) of the dogs studied were positive for at least one vector-borne agent with the prevalence being highest in the commercial breeding colony (24/97; 24.7 %).ConclusionsOur study confirms that B. vogeli, B. gibsoni, H. canis, and E. canis occur in China. Also, we present evidence that T. orientalis or a closely related organism can infect dogs.

“…In China, several studies have reported the prevalence of D. immitis in dogs, 12.7% in Shenyang city and 24.0% in Dandong city, northeastern China [ 13 , 14 ], 13% in Henan province and 31.2% in Xian city, central China [ 15 , 16 ]. The prevalence is 13.5% in southern China, such as Nanchang, Fuzhou, Guangzhou, Shenzhen, Nanning [ 17 ]. 61.3% in Chongqing [ 18 ], the seoprevalences of D. immitis were also found in Beijing (0.33%, 1/300) and Shanghai (3.3%, 1/30) [ 19 ].…”

The present study was performed to investigate the seroprevalence and risk factors for Dirofilaria immitis infection in cats from Liaoning province, northeastern China. From October 2014 to September 2016, sera of 651 cats, including 364 domestic cats and 287 feral cats (332 females and 319 males) were assessed. They were tested for the presence of D. immitis antigen using SNAP Heartworm RT test kit. In this population, the average prevalence was 4.5%. Age and rearing conditions (feral or domestic) were found to be associated with the prevalence of D. immitis. The prevalence was significantly higher in feral cats compared with domestic cats (8.4% vs 1.4%, P<0.01). There was no significant difference between males and females (4.7% vs 4.2%, P>0.05), but older cats (≥3 years old) showed a statistically higher prevalence compared with younger cats (<3 years old) in feral populations (16.8 vs 2.4%, P<0.01), while the difference between the age groups was not statistically significant in domestic cats (2.4% vs 0.51%, P>0.05), all these results suggest that outdoor exposure time may be one of the most important factors for D. immitis prevalence in cats. Results reveal that D. immitis are prevalence in domestic and feral cats in northeastern China, which indicates that appropriate preventive measures should be taken to decrease the incidence of feline heartworm disease in Liaoning province, northeastern China.

“…In the current study, this infection was investigated for the first time in shelter dogs located in the Thrace Region of Turkey by serologic, molecular and microscopical assays. The seroprevalence of the infection was reported as 1% in Iran [15] , 18% in India [16] , 13.5% in China [10] and 55.3% in Russia [8] . In Europe, the seroprevalence was recorded as 9.6% in Italy [17] , 2.4% in Spain [18] and 2.1% in Portugal [19] .…”

“…Heartworm disease has worldwide distribution and the rate of this infection has been increasing through the central and northern Europe [1] . Many researchers [8][9][10] reported the presence of the infection in different countries around the world. In Europe, the prevalence range of the infection reported between 0.2% [11] and 28.7% [12] .…”

Dirofilaria immitis is an important nematode of dogs and cats which causes fatal heartworm disease in their hosts. The aim of this study was to investigate the prevalence of D. immitis by serologic and molecular methods in shelter dogs, in the Thrace Region of Turkey. Blood samples were collected from 402 dogs in shelters which were located in four cities (Istanbul, Edirne, Tekirdag and Kirklareli) in this region. The blood smears were examined for the presence of D. immitis microfilariae under the light microscope. The commercial Snap3Dx test kit and PCR assay for amplifying the ITS-2 gene region were used for the serological and molecular analyses, respectively. The serologic and molecular prevalence of D. immitis was determined as 6.7% and 2.7%, respectively. D. immitis microfilariae were also determined in the blood smears of three dogs (0.8%). The distribution of the infection according to the provinces was 14.7% in Edirne, 11% in Kirklareli, 1% in Tekirdag and 0% in Istanbul. The occult infection rate was determined as 59.3%. This study revealed the presence of D. immitis for the first time in the Thrace Region of Turkey. This region is the transition point to Europe and obtained data in this study could contribute to the control of heartworm disease in the area. Keywords
